Background: Gastric cancer (GC) is one of the most prevalent cancers with a high rate of mortality in the world. In recent years, microRNAs (miRNAs) have been proposed to be involved in GC development. In this study, we aimed at investigating differential expression level of miR-155-5p, miR-15a, miR-15b, and miR-186 in GC. Methods: For this research, we used qPCR to investigate miR-15b, miR-155...

Introduction Polychlorinated biphenyls (PCBs), organic lipophilic pollutants that accumulate through diet and increase with age, have been associated polycystic ovary syndrome (PCOS) shown to affect microRNA (miRNA) expression. This work aimed determine if PCBs were circulating miRNAs whether there any correlations serum PCB/miRNA levels hormonal changes. Methods 29 non-obese PCOS healthy contr...

it has been well documented that preeclampsia (pe) has a common etiological background, but little is known about its linkage at the molecular level.non- coding rnas are critical posttranscriptional regulators ofgene expression.  this study was performed to determine whether peis associated with alterations in placental non-codingrnas expression. microrna(mir)-155-5p and long non-coding rna (ln...

Abstract Background Accumulating evidence indicates that dysregulation of miR-182-5p can serve as diagnostic and prognostic biomarkers for some cancers, whereas the role has not been explored in nasopharyngeal carcinoma (NPC). Our study aims to elucidate biological function NPC potential molecular mechanism involved. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was perform...

Abstract Study question Could microRNA profiling be a useful tool towards better understanding the pathophysiological mechanisms leading to non-obstructive azoospermia (NOA) due maturation arrest? Summary answer MicroRNA may an efficient method unveiling arrest pathophysiology as microRNAs constitute master posttranscriptional regulators of cell-cycle control during spermatogenesis. What is kno...

It is well known that microRNAs play a very important role in regulating reprogramming, pluripotency and cell fate decisions. Porcine induced pluripotent stem cells (piPSCs) are now available for studying the pluripotent regulation network in pigs. Two types of piPSCs have been derived from human and mouse embryonic stem cell (ESC) culture conditions: hpiPSCs and mpiPSCs, respectively. The hpiP...

Gene regulation in cells exposed to ionizing radiation (IR) occurs at the transcriptional and post-transcriptional levels. Recent studies have suggested that micro-RNA (miRNA) play a significant role in post-transcriptional gene regulation in irradiated cells. miRNA are RNA molecules 18-24 nucleotides in length that are involved in negatively regulating the stability or translation of target me...
